Version 0.2.4 - UNRELEASED

 * fixed careless import of Tkinter
 * fixed typo that breaks PyCAM for Python 2.6

Version 0.2.3 - 2010-04-05
 * GUI change: tool and process settings can be combined into tasks
 * store configured settings to a file in the user's home directory
 * added "material allowance" support for non-ODE calculations
 * added export of EMC2 tool definitions
 * added a warning dialog (GUI) for missing dependencies during startup (especially useful for Windows)
 * improved GUI for model scaling
 * allow to configure if the tool should move inside/along/around the boundary limits
 * fixed "overlap" calculation
 * prevent invalid input values (zero tool radius, ...)
 * fixed a bug that could rarely cause eternal loops of the PushCutter
 * reduced memory consumption of toolpaths for python 2.6 or above
 * disabled ODE as the default computation backend (due to this bug:
   http://sourceforge.net/tracker/?func=detail&aid=2973876&group_id=24884&atid=382799)

Version 0.2.2 - 2010-03-17
 * added a graphical installer for Windows (via distutils)
 * fixed broken commandline parameter "--template"
 * added workaround for ODE collision detection, that is broken under specific circumstances

Version 0.2.1 - 2010-03-09
 * fixed code that depended on GTK 2.16 (instead of 2.12)
 * view settings "light", "shadow" and "polygon fill" are now configurable
 * documented version problems with Debian "Lenny" and Ubuntu (before "Karmic")

Version 0.2 - 2010-03-04
 * added an alternative GTK interface with additional features:
  * configurable 3D view settings: model / toolpath / axis / drill progress / frame rate / colors
  * manipulation of the model: rotation, flip, swap, scale, move
  * saving the model to an ascii STL file
  * load/save processing settings from/to a file
  * handling of multiple processing templates (e.g. "Rough", "Semi-finish" and "Finish")
  * configure "material allowance" for a minimum distance between drill and model
  * configure the "safety height" for the machine
  * allow to manage and export (gcode) multiple toolpaths at once
  * based on GtkGlExt (for OpenGL)
  * visualize invalid processing setting combinations
  * configure "overlap" instead of "lines" and "samples"
  * configure "maximum step down" instead of "layers"
  * show a progress bar during calculations
  * basic lightning for the OpenGL view
 * improved performance by (optionally) using the "Open Dynamics Engine" (ODE) for
   collision detection
